Lead Service Lines in Marietta, GA

What you need to know

About 755,600 people in the Marietta area get water from 8 different water systems. The two largest are Cobb County (serving 695,000 people) and Marietta Board of Lights and Water (serving 60,100 people).

Lead service lines—the pipes that connect your home to the public water main—are a real concern in many US communities. These lines can leach lead into drinking water, especially in homes built before the 1980s. However, Georgia has relatively lower rates of lead service lines compared to older cities in the Northeast and Midwest.

The current status: The water systems serving Marietta have not reported known lead service lines in their inventories. That said, many water systems nationwide are still in the early stages of mapping their service lines, so incomplete data is common. An absence of reported lead lines does not guarantee none exist in your neighborhood.

What causes lead in water

Lead service lines are the most common source of lead in drinking water. The metal can leach into water—especially cold water and water that sits in pipes overnight—when the protective scale inside the pipe breaks down.

Not all homes have lead service lines. Homes built after 1986 are unlikely to have them (federal law banned their installation). Homes built between the 1920s and 1970s face higher risk, depending on local construction practices and soil conditions.

How to find out if your home has a lead service line

1. Contact your water utility directly. Ask if they have completed a service line inventory and whether your address appears on it. 2. Check your water bill or utility website. Many utilities now publish inventory data online or include it in customer communications. 3. Hire a plumber to inspect the line where it enters your home (usually in the basement or crawlspace). Lead pipes are dull gray and can be scratched with a coin.

If you discover or suspect a lead service line, you can have your water tested by a certified lab. The EPA and CDC recommend this, especially if you have young children.

Next steps for residents

  • Contact Cobb County (if that serves your address) or Marietta Board of Lights and Water and ask for their lead service line inventory status.
  • Request a copy of your home's service line record if your utility has completed mapping.
  • If concerned about exposure, visit the CDC's lead and health information or speak with your pediatrician.

How do I know if my house has a lead service line?
